Auto Glass Your front windshield does more than just keep the rain and bugs out. It is actually a structural component of your vehicle. It helps provide roof support in the event of a rollover and acts as a backboard for the airbags. Don't take chances with your family's safety. Our friendly staff and certified technicians will get you back on the road quickly and safely. Your satisfaction is guaranteed. Today's vehicles offer many high-tech auto glass features. From antennas,rain sensors,and heads up displays to acoustic interlayers,photovoltaic cells,and hydrophobic coatings ... glass installation today requires specific training and professional expertise. Below is a glossary of terms that can help understand some of the high-tech features in today's auto glass. Acoustic Interlayer- Glass having a thicker than normal vinyl laminate for noise reduction. Adhesive - A polyurethane product designed to bond glass to painted metal that is both strong and flexible. Its strength is measured in two ways: tensile and lap shear. Typical auto glass adhesives achieve tensile strengths of 1000 psi and lap shear strengths of 500 psi. AGSC - Auto Glass Safety Council. A non-profit organization dedicated to the safe replacement of auto glass Anti-Theft - Vehicle glass that is made of laminated glass & tempered glass sandwiched together to help prevent smash & grab theft. Butyl - An adhesive / sealant that was the primary material used to bond car windshields in the 60's and 70's launch crp129. Achieves lap shear strengths of only about 13 psi. Diversity Antenna - Combines the reception from 2 or more antennas on the vehicle. They work together to achieve superior radio reception. Usually appears as a thin brown or orange line inside the glass. Dot Matrix Shade - The traditional gradient shade band in the laminate is replaced by a dot matrix frit across the top of the windshield. These little black dots are painted onto one of the glass surfaces. Electrochromic Mirror - Also known as Auto-Dim Mirror. A rear view mirror that senses light and automatically dims. Encapsulated - A glass part that has a molding attached,sometimes at the top only,and sometimes around three or four sides of the glass. FMVSS - Federal Motor Vehicle Safety Standards,i.e: FMVSS #212 the barrier crash test,and #216 the roof crush resistance test. Frit - The black painted border around the perimeter of the glass. This painted area serves two purposes. First is aesthetics,it just looks better. Second,it blocks the sun's rays from deteriorating the adhesive that structurally bonds the glass to the vehicle. Heated Wiper Park Area - Windshield contains heater grids across the lower part of the glass where the wipers rest. These are usually visible as brown or grey lines running horizontally at the base of the windshield. Hydrophobic coatings - coatings on the exterior #1 surface that cause raindrops to become round and roll off the windshield automatically. HUD - Heads up display. Some of your vehicle's key instrumentation is flashed up onto the bottom of the windshield. This allows drivers to check speed,etc. without having to take their eyes off of the road. Infrared - A term used to describe Solar Coated glass. Laminated - A sandwich of two pieces of glass with a PVB layer between them. All front windshields are made of laminated glass. Properly installed windshields cushion an occupant's head during impact,act as a backboard for the airbags,and provide structural roof support in an accident. Laser Deletion Area - a solar coated glass that has a small area without coating to allow lasers to work through the glass. Light Sensor - A sensor usually located on the windshield that senses the absence of light and turns the headlights on. Night Vision - An infrared camera mounted on the vehicle which detects objects further ahead than headlights launch creader viii,and displays the images on a section of the windshield. O.E.M. - Original Equipment Manufacturer PVB - Polyvinyl Butyral. The vinyl layer between the two pieces of glass that make up a front windshield. Rain Sensor - A sensor usually located near the windshield's rear view mirror that senses rain and activates the wipers. Safe Drive Away Time - Actually,it should be called Safe Crash Time . The elapsed time after a front windshield installation that a vehicle would safely pass all the appropriate rollover and roof crush requirements. One hour minimum. Solar or Solar Absorbing - Glass that blocks out harmful ultraviolet and infrared rays thereby reducing the sun's damage and keeping the inside of the vehicle cooler. Solar Coated - During the manufacturing process,the inside surface of the outer layer of Non-Solar glass is coated with UV reflective film before the inner layer (PVB) is sandwiched between the outer and inner layers of glass.
